Just to be clear, a craniotomy is a surgical operation in which a bone flap is removed from the skull to access the brain. One could be from a severe TBI to relieve bleeding. Four would be extremely rare. For what underlying condition did he undergo four craniotomies?

"Is this normal behavior being 14 months in?"

No.

"We live in a rural area and do not have any resources."

If there are surgeons available to perform four craniotomy procedures my guess is there are some PhD level psychologists that can do an assessment,

Best to you all
